Keratoconus Treatment
Patient Reviews
I had cataract surgery with a trifocal IOL last week. A smart, three-dimensional lens was implanted. Within one week I was back to my normal social life, and my vision is 100%. Prof. Coşkunseven is an excellent surgeon and the technique he uses is truly the right approach. Do not hesitate — get your treatment done.

You have been in our prayers since 2009, dear professor. When everyone else was recommending surgery for my brother's keratoconus, we were fortunate to find you by chance — and so glad we did. Thank you for treating him with intracorneal ring segments back in 2009.

Dear professor, being able to see the world clearly is truly a miracle — you have touched my life in the most wonderful way and transformed my quality of life overnight. I am so glad I found you. You performed both the cataract surgery and the lens implantation in a single session and had me recovering in just one day.

Wishing you a long and healthy life, Prof. Coşkunseven. May those healing hands of yours continue to work wonders.

Hello professor, I am writing from out of town. Five years ago you performed an intraocular lens (IOL) implantation on my right eye and laser treatment on the other — I was extremely happy with both. Your warm, attentive manner felt like that of an older brother or a father. You are truly precious to us.

Dear professor, you performed laser eye surgery on me back in 2003 and it completely changed my world. I now live in the Netherlands. I would like my son to have the same procedure done. Thank you so much. Greetings from the Netherlands.
